This Deliverable provides the Data Management Plan (DMP) for AIDAVA. It is based on the European Commission Template for Horizon 2020 projects available at https://ec.europa.eu/research/participants/data/ref/h2020/gm/reporting/h2020-tpl-oa-data-mgt-plan_en.docx. AIDAVA has populated this Data Management Plan in line with recommended EC guidelines. It will be updated as the project proceeds. A DMP is an important component of any data intensive programme because it imposes a need for balance between protection of data, success of the programme and the potential for reuse of data. AIDAVA is unique as a project because the primary data handling is focused on data ingestion and curation as a tool to assist citizens in managing their own health data. The approach to developing the data management plan has included workshop discussions with partners at the October 2022 Kick Off Meeting in Maastricht and a dedicated data flow workshop held in Tallinn in December 2023. The details gathered were compared with the proposal and obligations on the partners as described in the consortium agreement. They were also compared with the developing Research Protocols for both the Breast Cancer and Cardiovascular Disease (CVD) use cases developed in Task 1. The results of the details gathered are presented as the Data Management Plan in Section 3 of this Deliverable. It concludes with the next steps and specification of updates in time for M40's second version of the Data Management Plan.
